As it shows from WDS, 1 series electric platform was prepared for EDC (or perhaps because it was just copied form 3 series), but commercially it never made it. KW DDC being readily available aftermarket solution, but an existing implementation of the BMW OEM alternative is too good to not look into.

He had a lot of trouble getting the M3 EDC (electronic damping control) to work properly. At first he only got the shocks to work in the "on" and "off" settings. ie too soft or full hard. Now he all three settings.

He had trouble with the 1M steering unit since it was different from the M3 one. He told me he ended up using a com box from a X5M that has a similar problem with all the electronic boxes talking to each other. Once he had all the "right" hardware... he was able to do the rest with simple "coding".
